• Source Matters: Collagen sourced from less-regulated markets may have a higher risk of heavy metal contamination.[https://wearechief.com/blogs/articles/whats-the-best-collagen-powder-in-australia]
• Testing is Key: Look for brands that conduct third-party testing for heavy metals.
• "Grass-fed" Doesn't Guarantee Absence: While grass-fed sourcing is often seen as a positive, it doesn't automatically mean the product is free of heavy metals.
• Be Aware of Prop 65: California's Proposition 65 sets limits for heavy metals in products. Look for products that test below these levels.
• No Guarantees: Even with testing, there's always a potential for trace amounts of heavy metals.

General Tips for Choosing a Collagen Powder:

• Third-Party Testing: Prioritize brands that use third-party testing to verify purity and heavy metal levels.
• Sourcing: Consider brands that source their collagen from reputable regions with strict regulations.
• Read Labels Carefully: Look for products with minimal ingredients and no artificial additives.
• Consult with a Healthcare Professional: If you have concerns about heavy metals or other health issues, talk to your doctor or a registered dietitian.
